Cancelling discovery mode fails/hangs after unsuccessfully connecting to a Bluetooth reader.

[mikado2005]

Summary

I generated a reader connection error by attempting to connect a BBPOS WisePad3 to an American account and location. It may be that generating any sort of connection error will also reproduce the issue. After that error occurs, any calls to the discovery Cancellable object hangs, by never calling its completion block. The completion block of discoverReaders is also never called.

Code to reproduce

Small sample project is here: https://planetbeagle.com/stripe/ConnectionError.zip

iOS version

iOS 16.6

Installation method

Integrated into app using CocoaPods.

SDK version

StripeTerminal (2.23.0)

@mikado2005 thanks for the report and sample project to reproduce! we learned about this regression last week and have a fix rolling out today. 2.23.1 should be published in the next few hours that will include the fix for this.

ran the provided sample app against the pre-release 2.23.1 and confirmed it no longer gets stuck, thanks again for that.

closing this one out as it should be fixed in 2.23.1+ (just missed closing the issue).
